Multisegmented one-dimensional hybrid structures of carbon nanotubes and metal nanowires were
fabricated using the alumina templates. Metal nanowires are first grown inside part of the
nanochannel using electrodeposition technique, which is followed by the growth of carbon
nanotubes using chemical vapor deposition. Well-adhered interfaces formed between the carbon
nanotubes and the metal nanowires. The hybrid structure reported here results in nanoscale metal
contact with carbon nanotube and will provide a solution to problem of using carbon nanotubes in
interconnects. Nanotube-nanowire interfaces for different metals have also been examined and are
